Cardano (ADA) is scheduled to upgrade its existing network they call it the Alonso Hard Fork. The biggest upgrade of this cardano has
privileges capable of facilitating smart contracts on its network. If the cardano smart contract really happens
do you think cardano will be able to become a rival to bitcoin, ethereum and binance?
Your opinion its appreciated in this discussion.

If indeed Cardano developed a smart contract system, but to compete with Bitcoin and Ethereum, I don't think it can compete. But if you become a competitor to BSC, it can happen. Although BSC is a blockchain system with low transaction fees, BSC is still very new to the blockchain concept.
